A Brief History Of Atom | Democritus to Quantum | Atomic Models

Could an object be divided into smaller and smaller pieces forever? - To answer this question the new concept emerged in science which known as Atomic theory. In this video I have explained in detail about the Atomic theory revolution in each period.

To know more about in this topic, I recommend to read this book :

You are great Klonusk . I keep watching ur video Everytime. Pls pin me

[hsimmortal]

The knowledge I gained from this experience far surpassed what I could have acquired through traditional classroom instruction.

[bbarwik]

I am fan of channels like Veritasium and Kurzgesagt and today I've found a new amazing channel like this. Love it! I hope your number of subscribers will skyrocket soon ;)

The heisenberg picture swap made my day🙌🏼

Ancient Greek Grammar Police, YouTube Surveillance Unit here:

Atomos (Άτομος) is masculine gender. Democretus would have been referring to atoms in the neutral gender as Atomon (Άτομον).

The word is a compound coming from the verb “temno” (τέμνω) meaning “to cut”, in its noun form “tomé” (τομή) meaning “the cut”. The first part of the compound is the negating “a” (α).

So, atomon is something that cannot be cut further (like “uncuttable”, if that’s a word).

GREAT VIDEO 👍

Broo Klonuskkk.. I remember myself thinking a week or so back that it has been a long time since you had uploaded.. and now it's here.. very excited to see!..

Not condescending and no pompous-azzery.
Rare and Refreshingly well done.

[gauravtak]

The best video I have ever seen about atoms .., you are just brilliant……brilliant…… excellent…..excellent and excellent Thanku for making this video

[markerguy]

Klonusk an imp update, pls mention that in Bohr's Model, the electron "energy" is not just energy but it's "BINDING ENERGY" because the -13.6 there implies that this energy is negative which isn't even possible as -ve energy results in "anti-matter" and we all know that electrons are not anti-matter, so pls mention that this is the Binding Energy which is the energy required to knock this electrons off of their orbitals..

What a brilliant presentation. I had read about Bohr’s atomic model in 1988 / 89. Orbitals, atomic number, wave particle duality, Heisenberg and such. I used to tell myself I know all these things. But in truth I knew only about their names! Your presentation brought the vague ideas I had in my head to light! Thank you!

[Vijay-bvcp]

Went through the content in my physics and chemistry class and never understood, but this video cleared everything.If there is a thing called Feynman
Technique, you have mastered it.Thank You Sir.

[atullya]

Thank you Klonusk, great work. These visuals helped me understand better than what was taught in class.

[storytimeg.andfriends]

Good video! 😄 but here are some corrections 'Anu'='Molecules' and 'Parmanu'='Atoms.'

[Barseik]

At around 21:03, the light spectrum goes from radio to micro, then ultraviolet, then visible with the shortest on the left. This is rather misleading, as one might think radio waves are shorter than ultraviolet. Same problem as the right hand side of the spectrum, X-rays being presented as longer than infrared.

Best work, everything in sequence and order, great animation work, .. Klonusk your great work is really very very helpful to future scientists..👏👏

[emenikevictor]

U are great teacher indeed , you perfectly made everything clear , thanks for that

[SubhrajitReang]

thank you very much sir, love you from INDIA

[capjus]

Amazing man, i studied but never seen such good explanation, very uncomplicated

[RobinjayEbuen]

awesome editing and story telling, more on chemistry pls thank u.

[mardenteixeira]

this was the best animation of atom models I've ever seen, great job!
